The latest edition, unveiled Monday after eight years of compilation, “unprecedentedly” increased its content by about one third, “highlighting social changes over the past decade,” he said.

“Nu” or “slave” is also added with a new meaning in words such as “Fang Nu”, or “house slave,” referring to people striving to earn money in order to buy an apartment at a time when housing prices soar. The case is the same with words such as “car slaves” and “credit-card slaves.”

“The inclusion of these various types of ‘slaves’ in the dictionary shows that these new disadvantaged social groups have garnered great attention,” Zhou said.

“The words have to be current, widely used by the masses, and likely to be around for a long time, but there are no specific rules for inclusion,” said an editor at the Chinese Academy of Social Sciences, the compilers of the volume, who declined to be named.

The seven words below offer insights into the movements and preoccupations of today’s China.[…]
